Document Type and Number:
WIPO Patent Application WO/2019/149202
Kind Code:
A1
Abstract:
A mainspring motor comprises: a housing (1); a mainspring box (2) and a transmission gear set (4) disposed in the housing (1), wherein a first gear (3) is sleeved around an external wall of the mainspring box (2) and is engaged with an input end of the transmission gear set (4); a main power output shaft (5), connected to an output end of the transmission gear set (4), wherein a second gear (6) is disposed on the main power output shaft (5); an acceleration gear set (7), engaged with the second gear (6) for transmission; and a brake switch (8), for engaging with the acceleration gear set (7) when carrying out braking. When a mainspring (11) is stored with energy and the brake switch (8) is detached from a braking gear (702), the mainspring box (2) rotates under the action of the mainspring (11), thereby transferring power through the transmission gear set (4) to the main power output shaft (5), and the main power output shaft (5) outputs the power.
